Characteristics of trade winds
What are the characteristics of westerlies?
They blow in the middle latitudes between 35 and 65 degrees latitude. They blow from the subtropical high-pressure belts towards sub-polar low-pressure belts. The winds blow from the southwest in the Northern Hemisphere and from the northwest in the Southern Hemisphere.
What is one that describes a trade winds?
The Short Answer:
The trade winds are winds that reliably blow east to west just north and south of the equator. The winds help ships travel west, and they can also steer storms such as hurricanes, too.
What are examples of trade winds?
For example, Central America. During mid-summer in the Northern Hemisphere (July), the westward-moving trade winds south of the north moving subtropical edge. It extends to north-toward the west from the Caribbean ocean into south-eastern North America (Florida and Gulf Coast).
What determines trade winds?
The Coriolis Effect, in combination with an area of high pressure, causes the prevailing winds—the trade winds—to move from east to west on both sides of the equator across this 60-degree “belt.”
What are the three types of trade winds?
On earth, winds are broadly classified into three categories: Primary Wind. Secondary Wind. Tertiary Wind.
What is another name for the trade winds?
The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth’s equatorial region.
Where do trade winds occur?
The Trade WINDs are a large-scale component of Earth circulation, occupying most of the tropics straddling the equator between approximately latitude 30 degrees N and latitude 30 degrees S, with a seasonal shift of the entire trade wind belt system about 5 degrees of latitude northward during summer (July) and …
What causes trade winds to weaken?
The strengthening and weakening of the trade winds is a function of changes in the pressure gradient of the atmosphere over the tropical Pacific. Ironically, the warming of the sea surface works to decrease the atmospheric pressure above it by transfering more heat to the atmosphere and making it more buoyant.
What is the difference between trade winds and westerlies?
Trade winds are the winds that flow from subtropical high-pressure belts to equatorial low-pressure belts. Westerlies are winds that flow from subtropical high-pressure belts to subpolar/circumpolar low-pressure belts. Both are permanent winds.
Which statement best describes local winds?
Which statement best describes local winds? They move over short distances.
Are monsoon winds trade winds?
The easterly winds that blow in the tropics near the equator are called trade winds. a. Winds that blow from the Indian Ocean and South Asia and which carry moisture are called monsoon winds.
What are called westerlies?
Westerlies: Westerlies are the Permanent winds that blow in the middle latitudes. They blow from the subtropical high-pressure belts towards sub-polar low-pressure belts. The westerlies of the Southern hemisphere are more robust and constant than the westerlies of the Northern hemisphere.
How are trade winds caused Class 7?
The surface air that flows from these subtropical high-pressure belts toward the Equator is deflected toward the west in both hemispheres by the Coriolis effect. These winds blow predominantly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere.
Why do trade winds weaken?
The strengthening and weakening of the trade winds is a function of changes in the pressure gradient of the atmosphere over the tropical Pacific. Ironically, the warming of the sea surface works to decrease the atmospheric pressure above it by transfering more heat to the atmosphere and making it more buoyant.
What is the difference between trade winds and westerlies?
Trade winds are the winds that flow from subtropical high-pressure belts to equatorial low-pressure belts. Westerlies are winds that flow from subtropical high-pressure belts to subpolar/circumpolar low-pressure belts. Both are permanent winds.
